ALSA: hda/cs8409: Add quirk for CDB35L56-FOUR-HD

Browse source 
Adds quirkiness for the Cirrus Logic CDB35L56-FOUR-HD board.
The quirk must be forced by model name "CDB35L56-FOUR-HD"
because there isn't a unique SSID that can be used. For example
in /etc/modprobe.d:

options snd-hda-intel model="CDB35L56-FOUR-HD"

The CDB35L56-FOUR-HD is not a complete PC. It is an add-on audio
board that requires a host system and replaces the normal HDA codec
on the host. Because of this there isn't an SSID that uniquely
identifies this configuration. Also, the usual host board is an
Aaeon UpXtreme, which doesn't have a unique SSID.

Because of this, the quirk must be forced by a module param.
This is acceptable because it is a development board, not an
end-user system, so there is no need for it to be detected
automatically.
